System information

1. Add a client entry for AP1 to the clients.conf file:
client 192.168.101.0/24 {
secret = secret
shortname = my-ap1
}
Note: The secret is the same as the one added to the RADIUS Secret field in the
D-LINK-NET1 Wireless Network Configuration.
Similarly add client entry for AP2.
2. Add the user dlink with password admin to the users file as:
dlink Auth-Type := EAP, User-Password == "admin"
3. Restart the RADIUS server (you must restart it after you make any changes to the
configuration file).
4.5. Verifying the Configuration
6. On Unified Switch 2, click Monitoring Æ Access Points Æ Failed Access Points and add
AP2 to the Valid AP database on Unified Switch 2.
7. From a wireless client, connect to AP1 and verify that you can see the SSIDs for the
following:
• Guest Network
• D-LINK NET1
• D-LINK NET2
8. Connect to D-LINK-NET1 from a wireless client to verify that WPA2 authentication is
required.
9. After connecting, check the IP address that the switch DHCP server assigned.
10. Start the Roaming Test.
4.6. Testing the L3 Authenticated Roaming Feature
4.6.1. Simulated Roam via Power Down of AP
The following procedure shows how to perform an L3 Tunnel roaming test.
1. Use your laptop to test wireless connection by associating to the “D-LINK-NET1” SSID
Network, and check if you’re getting the IP address correctly from the Unified Switch’s
DHCP server on the Tunnel subnet after properly authenticating via WPA2.
2. Once wireless connectivity is confirmed, you can check which AP your laptop connects to
[ WLAN/ Monitoring/ Client/ Associated Clients ].
3. Start to Ping one of the LAN interfaces (172.17.5.253 or .254) or its loopback interface
( 192.168.10.254 ).
4. Disconnect the AP which your laptop is connecting to and see how soon you can roam to the
other AP. Normally 1 ping loss is observed when roaming. You will also observe that the
client will not re-authenticate with the RADIUS server further decreasing the necessary roam
delay (Note: this action requires client support). (Note: Please see section 3.6.1 below for an
alternative mechanism for simulating a roam)
